GRAlN-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 666,552, dated January22, 1901.

Application filed August 28, 1897. serial No. 649,858. \No model.)

To a whom it may concern:

Be it known that I, JOSEPH B. PEDRICK, a resident of Columbus, in thecounty of Bartholomew and State of Indiana, have invented certain newand useful Improvements in Grain-Separators; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to an improvement in grain-separators, the objectbeing to provide means for effectually separating the straw, grain, andchaff and distributing them in their separated condition; and itconsists in certain novel features of construction and combinations ofparts, which will be hereinafter described, and pointed out in theclaims.

In the accompanying drawings, Figure 1 is a longitudinal section of theentire machine. Fig. 2 is a detail view of one of the carriers. Fig. 3is a plan and elevation of a portion of a carrier in which asprocket-chain is employed in its construction. Fig. 4. is an enlargeddetail of the vibrating mechanism. Figs. 5, 6, '7, 8, 9, l0, and 11 aredetails of parts.

A is the frame or casing of the machine, carried in the usual mannerupon suit-able wheels 1 1. In the forward end is journaled the customarycylinder 2, and beneath it is located the concave 3. Extending upwardlyupon an incline from this cylinder is an endless carrier B, and frombeneath the rear end of this elevator B is a second endless carrier 0.These carriers are similar in many respects; but as they differ in somedetails of construction they will be described in the order mentioned.Carrier B comprises in the main a series of two belts or sprocket-chains5 5, as the case may be, and cross-slats 6 6, secured at their ends tothe chains or belts. The slats are preferably inclined on their upperedges, as shown, in order the more readily to catch and elevate thestraw and grain as it is deposited thereon by the threshing-cylinder andbeater 7. A riddle of coarse mesh is formed between the slats by meansof rods or wires 8 8, secured to one side of each slat below the planeof the top surface thereof and extending to or nearly to the nextadjacent slat. These free ends of the rods or wires 8 8 rest lightlyupon rods 9 9, which extend transversely of the carrier, said rods beingsupported by brackets 10 10, secured to the under side of the slats. Thecarrier is supported by and travels around rollers 11 11 orsprocket-wheels 12 12, by which it is driven, accordingly as belts orsprocket-chains are used, as indicated, respectively, in Figs. 1 and 2.Provision is made for constantly vibrating this carrier, and it consistsof an arm 13 on each end of a rock-shaft l4, journaled in the sides ofthe frame or casing of the machine or casing. The outer ends of thesearms are furnished with rollers 14 14: or sprocket-wheels 15 15, overwhich the belts or sprocket-chains pass. One of these arms 13 isprovided with a lever 16. A pitman 17 extends from an end of this leverto one of the rollers 11 or sprocket-wheels 12, and in this manner asthe roller rotates the arms are vibrated. This motion keeps up aconstant agitation of the carrier, and the grain is sifted and separatedfrom the straw during its passage through the machine. As has beenstated, the other carrier C is for the most part similar to carrier B.In lieu of the vibrating arms for shaking and agitating the carrier apair of shafts 18 18, having sprocket-wheels 19 19 loose thereon, areemployed. These shafts have cranks 20 20 at their ends, which arejournaled in the frame or casing of the separator. The cranks of the twoshafts 18 18 extend in opposite directions, so that as the shaftsrevolve the sprocket-wheels alternately rise and fall, lifting anddropping the carrier, thereby facilitating the shaking, spreading, andseparation of the grain and straw. In the carriers the rollers 14 andWheels 19 (which with the parts that move them constitute agitators) aredisposed above lines passing longitudinally through said carriers andthrough the bearings thereof. A beater 22 and toothed drum 23 arelocated in and above the space between the two carriers.

These rotate and insure the passage of the material from one carrier tothe other.

Beneath the carrier B is located an upwardly-inclining drag-carrier24,and beneath the carrier 0 is an inclining board 25, against which theslats travel downward in their 2o drum.

clined planes 26 26, extending its full length.

This drum is rotated rapidly, and cooperating with it is a concave 27.The latter is hinged at 28 to a plate 29. With its free end a rod 30 ispivotally connected. This rod extends up loosely through an eye 31 inthe arm 32 of the rod 33, and a spring 34 above the eye sustains thefree end of the concave by hearing upwardly beneath the head 35 on therod. The rod 33 may be turned to raise and lower the concave by settingthe arm 36 in its outer end between teeth of the segment 37. Within theconcave. are provided inclined planes 38 38, which extend in the reversedirection from those on the scouring- A fender 39 is located in rear ofthe scouring-drum in position to prevent the grain from being thrown toofar by the drum in its rotation.

Beneath the scouring-drum is located a fan A casing 41 extends aroundthis fan. It is provided with a hinged section 42. This is raised andlowered by a handle 43, which extends outside of the frame or casing andlooks into a segment thereon. The handle is on 0 the end of a shaft orrod 44, and an arm 45 riddles 48 and 49.

The various parts are driven by belts (not shown) passing over pulleyson the shafts of the several parts to be driven. Oonveyers, elevators,and such other accessories as are 0 commonly used in similar machinesare employed in this.

Slight changes might be made in the form and arrangement of the severalparts described without departing from the spirit and scope of myinvention, and hence I do not wish to limit myself to the exactconstruction herein set forth; but,

Having fully described my invention, what I claim as new, and desire tosecure by Letters 50 Patent, is

1. In a grain-separator, the combination with a carrier consisting ofaframe,sprocketwheels mounted in said frame, sprocketchains passing oversaid sprocket-wheels, and

cross-slats connecting said sprocket-chains,

of two cranks disposed within said carrier and spaced apart, and twosprocket-wheels mounted loosely on each crank and all in constant meshwith the sprocket-chains of the carrier, whereby, when the cranks areoperated, the carrier will be vibrated without hammer or' jarring effectand impart motion to the carrier.

2. In a grain-separator, the combination 6'3 with end supports, of anendless carrier passing over the same and comprising parallel chains orhands and cross-slats secured to and connecting said chains or hands,means located within the carrier at respective sides or the longitudinalcenter thereof and in constant engagement with the carrier and devicesfor operating said means to raise and lower the carrier bodilyalternately at respective sides of its longitudinal center.

3. In a grain-separator, the combination with an endless carriercomprising parallel chains or hands and slats connecting said chains orhands, and end supports for said chains or bands, of two sets of wheelsmounted within the carrier at respective sides of the longitudinalcenter thereof and in constant engagement with the carrier and means forraising and lowering all the wheels of each set in unison and for sooperating the respective sets of wheels alternately.

4:. In a grain-separator, the combination with an endless carrier andend supports therefor, said carrier comprising a series of chains orhands and a series of cross-slats connecting said chains or hands, ofcranks havingbearings for wheels at respective sides of the longitudinalcenter of the carrier, two series of wheels mounted on said bearings soas to support the carrier at respective sides of the longitudinal centerof the carrier, and means for operating said cranks to raise and lowerall the wheels of each set simultaneously and operate the respectivesets of wheels alternately.

5. In a grain-separator, the combination with end supports and a carrierpassing over said end supports, said carrier comprising a series ofchains or hands and cross-slats connecting said chains or bands, of twoshafts passing through the carrier at respective sides of thelongitudinal center thereof, each shaft having a series of cranks equalto the number of chains or hands and all the cranks of each shaftprojecting in the same direction, a wheel mounted on each crank and inconstant engagement with the carrier and means for operating thecrank-shafts to raise all the wheels on each simultaneously and raisingthe respective sets of wheels alternately.

6. In a grain-separator, the combination with end supports, of a seriesof endless chains or hands passing over said end supports, a series ofcross-slats connecting said chains or bands, a series of fingerssupported by each cross-slat and projecting toward the next adjacentcross-slat, a series of wheels mounted within the carrier between thecenter and each end of the carrier and in constant engagement with thechains orbands and means for raising and lowering all the wheels of eachseries simultaneously and for operating the respective series of wheelsalternately.

7. An endless carrier comprising belts or chains, cross-slats, bracketssecured to the under sides of each cross-slat, rods extending through.these brackets and lying parallel with the cross-slats, short rods orwires projecting from each cross-slat below the plane of the top surfaceof the slat and extending jacent cross-slat so as to be normallydisposed in planes below the top surfaces of the crossslats and meansdisposed under the belts or chains for raising and lowering them,substantially as set forth.
